强酸-弱酸混合体系中准确滴定强酸的研究     

马荔  张卫  陈虹锦  梁竹梅  谢少艾  李梅 《实验室研究与探索》2011,30(2):5-8

为准确滴定出强酸-弱酸混合体系中所含强酸的量,需考虑在不同的准确度要求条件下,混合酸体系中弱酸的浓度范围要求。基于混合酸滴定过程终点误差的2个来源分析,提出了混合酸体系中终点误差(TE)计算的新方法。在指定的终点误差要求和强酸的浓度范围条件下,计算了HCl-HAc、HCl-六次甲基四胺盐两种混合酸体系中HAc、六次甲基四胺盐浓度范围要求,随着各酸碱指示剂变色点pH值的增大,两弱酸浓度的上限要求逐渐减小。在|TE|=1%条件下,当HAc、六次甲基四胺盐浓度分别低于1.18和0.135 mmol/dm3时,可采用任意酸性指示剂准确滴定0.1 mol/dm3浓度范围的HCl含量;而当两弱酸浓度分别低于10.6和10.5 mmol/dm3时,准确滴定出混合酸体系中1.0 mol/dm3的HCl含量亦可采用任意酸性指示剂。  相似文献   

甘油溶液体变模量与浓度关系的实验研究     

刘艳峰  刘竹琴 《实验室研究与探索》2011,30(12):50-51,74

基于声速测试仪,利用时差法测量了超声波在不同浓度甘油溶液中传播纵波的速度,结合波动学理论间接求出了不同浓度下甘油溶液的体变模量.对甘油溶液的体变模量与其浓度的关系进行了定性和定量的研究与分析,给出了甘油溶液的体变模量与其浓度的关系图及线性拟合方程.研究结果表明,随着甘油溶液浓度的不断增加,甘油溶液的体变模量也随之增加,而且甘油溶液的体变模量与其浓度呈线性关系.这一研究结论在材料力学、化学工业以及进一步研究液体力学特性等方面有着重要的参考和应用价值.  相似文献

Clinico-Biochemical Correlation Between Psoriasis and Insulin Resistance     

Suparna Dhara  Anindya Dasgupta  Jayanta Kumar Rout  Ushasi Banerjee  Sayantan Dasgupta  Arindam Ghosh 《Indian journal of clinical biochemistry : IJCB》2015,30(1):99-103

Psoriasis is a chronic inflammatory disease associated with an increased insulin resistance, obesity and cardiovascular risk. The present study was aimed to assess insulin resistance and pattern of body fat deposition in psoriasis. Body mass index (BMI) and waist circumference (WC) were measured in 40 psoriatic patients and 46 age- and sex-matched control subjects. Fasting blood glucose (FBG) and serum insulin level were measured by standard photometric method and ELISA respectively. HOMA-IR (homeostatic model of insulin resistance) was calculated by appropriate software. The results indicated that case and control groups were comparable in terms of age and sex (p = 0.934) with an increased prevalence of psoriasis among male subjects (60 %). FBG and mean WC between the two groups were statistically not significant (p value = 0.271 and 0.21 respectively). BMI was significantly higher in case group compared to the control group (p = 0.049). Serum insulin level and insulin resistance in the psoriatic patients were significantly higher (p value <0.001). Multiple regression analysis revealed that insulin resistance (measured by HOMA) was dependent on BMI and WC at a significance level of p < 0.001 and 0.043 respectively. Therefore, the psoriatic patients in this region have significantly high amount of fasting serum insulin level along with an increased IR though their FBG level remains normal. Furthermore, these abnormalities are significantly dependent on total body fat as well as abdominal fat deposits. We suggest that psoriatic patients need to be evaluated for metabolic syndrome and managed accordingly.  相似文献

Tracking of physical activity in pubertal boys with different BMI over two-year period     

Triin Rääsk  Kenn Konstabel  Jarek Mäestu  Evelin Lätt  Toivo Jürimäe  Jaak Jürimäe 《Journal of sports sciences》2015,33(16):1649-1657

We examined the tracking of physical activity (PA) measured by accelerometers and subjective self- and parental reports in normal weight and overweight and obese pubertal boys over two-year period. In total, 156 boys with mean (±SD) age of 11.53 ± 0.76 at baseline and with mean age of 13.94 ± 0.74 at 2 year follow-up were studied. At baseline and approximately two years later, the boys completed self-report questionnaire and wore an accelerometer for seven consecutive days. On the basis of first year assessment’s body mass index (BMI), the children were grouped as normal weight and overweight and obese groups according to BMI cut-offs. Tracking correlations of objectively measured PA and subjectively measured PA were fairly similar across the 12–14 year-old-boys weight groups over two year period. Tracking correlations of objectively measured PA and subjectively measured PA were not significantly different over two-year period between both BMI groups. The results of the study show that pubertal boys objectively measured PA decreased over two-year period and so the boys started to be less active in their pubertal period.  相似文献   

基于黑龙江省农村冬季群众性体育的撑橇运动推广研究     

刘万鹏  董晓琪 《冰雪运动》2015,(6)

我国北方具有宝贵资源与先天的气候优势,开展各类冰雪运动的条件充足。冬季的群众性运动数不胜数,撑橇源自于北方民间历史悠久、覆盖地域广阔的“冰爬犁”,是极具民族特色的民间传统体育活动,是我国北方一种特有的民族体育资源,为我国北方民众传承和享用,承载着我国北方民众悠远深厚的冰雪运动文化。农村地广人稀,江河颇多,一到冬季江河结成冰就可以作为撑橇运动的场地,场地充裕,而且撑橇是由黑龙江省体育局批准在黑龙江省率先推广新兴冰上橇类运动,填补了我国世界橇类运动空缺的项目。经调查和研究表明,农村群众性撑橇运动的推广存在着很多制约因素,根据这些制约因素给出相应的解决方案,为更好地推广撑橇运动提供借鉴。  相似文献   

Impacts of equity structure on audit fees: Evidence from Chinese A-share listed companies in Shanghai Stock Exchange     

LI Zhou  SONG Li-hua 《重庆大学学报(英文版)》2015,14(4):155-163

Based on the data of 923 Chinese listed companies in 2013 to 2014, we investigated the impact of company equity structure on audit fees from the perspective of cross section and period duration. It is found that there is a positive correlation between the proportion of state-owned shares in listed companies and audit fees. To be more specific, there is a U-shaped relation between audit fees and equity concentration which is represented by the proportion of the largest shareholder. And the equity restriction ratio, represented by the sum of the proportion of the second largest shareholder to the tenth, has a positive effect on audit fees.  相似文献
